Usage

Starting the Erlang Process

1. Navigate to the project directory and install deps :

   cd examples/erlang-bridge/src
   
   yarn install

2. Replace RPC_URL in sdk.js with the actual RPC URL and set the chain parameter to which chain you want to connect:

   const rpcProvider = createPublicClient({
     chain: mainnet,
     transport: http('RPC_URL'),
   });

3. Start the Erlang shell:

   rebar3 get-deps && rebar3 compile

   erlc main.erl

   erl -pa _build/default/lib/*/ebin

4. In the Erlang shell, compile the main module:

   c(main).

5. Start the Node.js process from Erlang and get the port:

   {ok, Port} = main:start().

6. Define the parameters and call the get_rewards_from_chain function:

   Params = [
       {<<"address">>, <<"0x">>},
       {<<"stepBlock">>, 10000},
       {<<"back">>, {<<"days">>, 1}}
   ].
   
   Result = main:get_rewards_from_chain(Port, Params).
   • address: Ethereum address for which to retrieve rewards.
   • stepBlock: Max blocks in 1 query - depend on the RPC capabilities and pricing plans
   • back.days: Number of days to step back.
